The first is nice... but it quickly rolls down the hill and parks underground. The second looks like one of her friends took it. I'd suggest you start paying attention to facial qualities... as the others look like she hasn't slept in days.

Also, the color of the last is orange... not flattering, unless she's an Umpa Lumpa pin up girl.

Image 1 looks about the best from your set of pictures but seems to need some contrast or levels used. There also appears to be different colors on these. While she looks more tan on 1 and 5, images 3 and 4 she looks more pink and there are some kind of stripes going through her arm on number 4 as if it were scanned from a magazine or something similar.

Darn, I am glad I don't have feelings to get hurt. Looking back through the comments and the shots, I thank you and will try to figure out what happened with the color. New laptop may have something to do with it, or at least my only excuse for now.

In my humble opinion, every image we shoot with skin tones needs to be edited. I have found that in the auto white balance mode, it will give you colors it sees in the picture and tint everything with that color, including skin tones.

In a controlled environment, such as a studio, we can set the white balance with a custom value. But outside and moving around, it is a lot of extra work and may annoy your model.

What I like about Elements 4 is the ability to set an eye dropper on a black, white or grey part of your image and with one click, the whites are white and the skin tones look natural. Again, you need to do this with every image you edit.

I might suggest you work the contrast on your images so that they are consistent. Go for 256 values of light in levels and you get white whites and black blacks...look at the first image and see that the teeth and eyes are not very white. #4 is much better, but maybe too contrasty.
